how much boost are you using for how much power?

Post by donger » Sun Jul 10, 2016 10:42 pm

when I was running 10 psi I had 300rwph . looking to increase to around 20 psi in fun mode . Now that my motor is getting rebuilt stronger , new mount for the turbo and plastic parts need to be replaced with custom steel parts to take 20 psi.

I am assuming you are talking about replacing the plastic UIM/LIM with non plastic parts? This died a few years ago but wasn't [articularly nice (heavy) http://www.rx8clubsingapore.com/viewtopic.php?t=4975. Its my understanding that the stock plastic parts are good for upwards of 16-20 PSI without issue. I know ive seen 16PSI pre-intercooler many times and had no issues.

Yep got that part. Pointing out that you may not need to change that part. Assuming you follow normal process, you would probably start in a safe range, say 12 PST and make sure that works, then step it up somewhat, rinse and repeat. Personally I'd just have a spare UIM and LIM on hand and if you do happen to blow one, put the spare on, hold off on the higher boost level until you can get a new intake set up made up as there are no off the shelf options.

Also of note is that the OEM intake is highly tuned.
